Welcome to the wonderful world of the DR650. What year is your DR, how many miles? Did you drop the bike on the left or right side? Since it's unusual to bend anything that's related to the chain, chances are the bike was buzzing before you dropped it. It's simple enough to get down on your knees next to the bike and follow the chain around its diameter, look for something touching. The swingarm is the aluminum thingy running from your frame to the rear axle. Chain: There is supposed to be a fair bit of play, both up-n-down and side-to-side. There is a rubber piece running along the bottom of the swingarm, you should be able to push the chain up and touch it; at the rearmost end of the rubber. Loosen it back up. The worst thing for your driveline is a chain that's too tight, don't make adjustments that you don't understand. :ddog According to my ex-wife, so is I. How old are you, any mechanical experience (you know, are ya a tool guy)? Fill in your profile (country or state, guys warm up to ya quicker), learn how to post pics (everybody loves pics), don't touch anything until you post a pic and ask what you need to do. It's mid winter, everyone is bored and looking for a new kid to teach how to do things right.
